Logic Equations
Logic Functions
The “AND” Operator
Requires that each argument be active.
Example: AND(Z02,Z05,L2D12)
All three arguments in the equation must be active for the logic zone to be activated
.
The “OR” Operator
Requires that any argument be active
Example: OR(Z02,Z05,L2D12)
If any one of the three arguments in the equation is active the logic zone will be activated.
The “NOT” Operator
Inverts the state of the argument (activated to deactivated OR deactivated to activated).
Example: NOT(Z02)
The logic zone will remain activated until the argument activates.
If the argument activates the logic zone will deactivate.
The “ONLY1” Operator
Requires that only one argument be active.
Example: ONLY1(Z02,Z05,Z09)
If only one of the arguments activates the logic zone will be activated.
The “ANYX” Operator
Requires that the amount of arguments specified by the number preceding the arguments be active.
Example: ANYX(2,Z02,Z05,Z09)
If any two or more of the arguments are in alarm the output point will be activated.
The X amount may be a value from 1 through 9.
The “XZONE” Operator
Requires that any combination of two or more input devices programmed to a zone be active.
Example: XZONE(Z02)
If any combination of two or more initiating devices that have been mapped to this software zone
come into alarm, then outputs mapped to this zone will activate.
The “RANGE” Operator
Each argument within the range must conform to the requirements of the governing function. The
range limit is 20 consecutive arguments.
Example: AND(RANGE(Z1,Z20))
Zone 1 through Zone 20 must all be active to activate the logic zone.
Time-based Functions
The panel supports three time-based functions: DEL, SDEL, and TIM. Special rules apply to an
equation containing a time-based function:
•Only one time-based function may be used in an equation.
•The time-based function must appear only once, as the first entry of the equation.
•It may not be nested within parentheses in the equation.
